XCode 5负荷碰撞

Question

突然间，我的XCode 5项目每次打开它都会导致XCode崩溃。--这不是由源代码管理引起的，因为这是禁用的。这是堆栈串。

Answer 1

这似乎是由IB约束引起的，我们在其中一个视图上指定了IB约束。以下是我为“解决”这一问题所做的努力。

1. 打开导致问题的*.storyboard文件
2. 如果您碰巧知道是什么“场景”导致了崩溃(例如，如果您正在处理某一项，而它突然在您身上崩溃)，那么在XML中找到该场景。
3. 找到场景中的所有<constraints>部分，并开始逐个删除它们，同时继续尝试打开XCode。

一旦你找到了导致问题的约束，你应该是好的。希望这能帮别人节省点时间。

你试过删除插件吗？它们位于以下目录：

~/Library/Application Support/Developer/Shared/Xcode/Plug-ins

如果不尝试以下操作：

1. 删除派生数据rm -rf ~/library/Developer/Xcode/DerivedData
2. 删除Xcode并重新安装吗？

Answer 3

我认为您可以通过将更改还原到您添加AutoLayout之前的最后一个故事板来解决这个问题。Autolayout Xcode的新警告和提示功能是罪魁祸首。这个问题也应该向苹果公司报告。
